How to check sensitive words before submitting articles in ajax
This article mainly introduces how ajax implements the review of sensitive words before submitting the article, which is very detailed and has a certain reference value. Friends who are interested must read it!
So I thought of returning the Boolean value passed by Ajax on submission. In fact, the function get2 () passed by Ajax is a subfunction of chkfull (bt) and cannot be passed to an external function, and alert () does not work. So simply cancel the submit type of the submit button and use Javascript to automatically submit the form after a series of checks.
The code is as follows
HTML
The code is as follows:
/ / Note the type is "button"
/ / embed a hidden text box to pass a value to Ajax
The Javascript part of Ajax
The code is as follows:
Function chkfull (bt) {
Var content = document.getElementById ("usercontent") .value
If (content== "")
{
Alert ("text is required.") / / determine whether the content of the article is empty
Return false
}
Else
{
Var xHRObject=false
If (window.XMLHttpRequest) / / judge the browser kernel
{
XHRObject=new XMLHttpRequest ()
}
Else if (window.ActiveXObject)
{
XHRObject= new ActiveXObject ("Microsoft.XMLHTTP")
}
Function get2 () / / defines the get2 function to prepare for onreadystatechange. This function cannot be placed after xHRObject.onreadystatechange=get2;
{
If (xHRObject.readyState==4 & & xHRObject.status==200)
{
Var serverText=xHRObject.responseText
If (serverText== "sense")
{
If (confirm ("are you sure you want to publish your article with sensitive words?\ n\ r [Yes, publish] will be reviewed, please wait.\ n\ r [No, do not publish] will return to the interface, please modify the words.")
{
Bt.value= "submitting"
Bt.disabled=true;// close button
Document.getElementById ("userchksense") .value = "sense"; / / change the value of userchksense to sense, so that post to add.php can directly check whether to lock the article without having to check the article again.
Document.form1.submit (); / / submit the form
}
Else// seems a little redundant, but it's safer this way.
Return false
}
Else
{
Bt.value= "submitting"
Bt.disabled=true
Document.getElementById ("userchksense") .value = "nonsense"
Document.form1.submit ()
}
}
}
Var title=document.getElementById ("usertitle"). Value
Var tag=document.getElementById ("usertag"). Value
Var intro=document.getElementById ("userintro"). Value
Var content=document.getElementById ("usercontent"). Value
Var v = "title=" + title+ "& tag=" + tag+ "& intro=" + intro+ "& content=" + content
XHRObject.open ("POST", ".. / ajax/ajax.php", true)
XHRObject.setRequestHeader ("Content-Type", "application/x-www-form-urlencoded")
XHRObject.onreadystatechange=get2;// the get2 here cannot be parenthesized, otherwise the return value of the function is assigned to a variable instead of the function itself to xHRObject.onreadystatechange (Note 1)
XHRObject.send (v)
}
}
